, This inventionfrelates to improvements in machines for picking and hashing corn and especially to the means; for delivering the proached by aninclined, chute tothe upper end of whichthe ear's'of corn ar-e deliveredV ears of corn from the picking rolls to the ,hnsking rolls; itmore l-'Qarticularlyvrelating to l'an arrangement whereby the ears of corn are fed to theuhusking `rolls ina more umform.manner." U l f In .machines ofy this character 1t has been the practice to employjahusking unit .ap-

by an endless conveyor arranged at 'right- 4angles ,to the directionofthe length ofthe vided longitudinally thus diyiding the ele-j j fvated lears of corn-With/one side leading to one half of the husking unit andtheother y chiite." In the present case 'the chutefis disideto the other half of theunit7 the'pa-rti-y the'conveyor to both sides of the partiti'onl in which is *higher thanfthe other.

Di-iiiculty has been experienced in securing a' uniform discharge of the ears from the two channels mentioned, where such channels are of aiixed character, due to varying f conditions inthe corn. If the corn iscomf fparatively green, 'the tendency is forv the maj orY portion of it to discharge through the low'y channel to they near side of the chute, While on the contrary if'the corn isdryj the l tendencyy is for. themajor fportionlrof the ears to hold tothe conveyor and discharge HiA i Vand trash Vthan the greenerones.

This tendency is' largelyfdue tothe fact that they dryears .are V"miXeLdwith a larger' proportion ofblades .Itis one-of' the objectsoflmy vinvention to provide `means to f obviateY this difficulty Y' ywherebythe ears 4of corn may be delivered more uniformly tobothsides ,of the chute 4 v re'g'ardless 'of thecondition ofl the' material;

The endlessconveyory which conveysfthe i earsl of foorn from'fthe `icking rolls tothe chute leading to thehus iung roll consists" vof which are connected a sheet metal pan 5j and over which passes 'a pair of sprocket chains 6 connected by slats?. f The sprocket chains pass about sprocket wheels 8. ony the "upper la pair of inclined angle ironsfi carryingside l Wall members 4t and to the under sidesof ends of the'lstandards 8 and also idlers 9 carried by arms Vi() pivoted to the standardfs;

The ears ofcorn are carried up the inclinedpan yby the Vslats and are discharged 'atjthe upper Vend-thereof. Two

This partijtio'n'member has ya bottom 26 which restsupon and is secured to the member26`.v The other auxiliary partition mem- -bending the side edges ofthe member 26into are-low enough to permit the ears of corn to vdrop into either oneof ther channels divided respectivelyftherebyto prevent over-'crowd` Y ingj of Aany channel and-also serves to insure the ears vof corn beingfed uniformly end-0n t0 the husking 'rolls.7 Y
